Abstract: Abstract: During the coronavirus (COVID-19) pandemic, many people work from home and hold meetings

online from the past decade video conferencing become more popular. It is very efficient, distance learning

and very effective now a days. We have lots of channels for video conferencing like Zoom, Ms teams,

hangouts and Jitsi meet. This can be operated over the mobile phones our personal laptops. But we do not

have any application by which we can use the video conferencing over the Android Tv directly. There are

many steps by which we can broadcast our mobile or laptop screen over the Android Tv but there is no such

application by which we can directly use the application directly on the Android Tv screen. In this Research

paper, by using the API integration of the Jitsi meet or connectivity, Android Tv application can be created.

From the last year, IT sector becomes more powerful because of the Work from Home Policies due to

Pandemic Situation. All the work is going online, which is called distance video conferencing. For the

effective learning we need a big screen, which would be very effective for distance learning. With the help

of The Android Tv video conferencing application USER can learn the things quickly and without any

trouble over the big screen. It will be very helpful for the students at Schools, Universities and for the

employees of corporate world.

1 INTRODUCTION

Distance learning becomes more popular for holding

the meetings over the different channels of

Conferencing, innovation has arrived at a degree of

steadiness, convenience and moderateness which

allows its utilization in genuine instructing situations

instead of exploration projects. In this research

work, Android tv conferencing app is being made by

using the Integration of Jitsi meet into the

application. Now a days, video conferencing

becomes very popular for distance learning and

work from Home for the corporate world. The

utilization of video is being hailed as the following

development in electronic correspondence.

Numerous organizations are creating frameworks to

help such ideas as virtual groups, working from

home, and remote conferencing. Video conferencing

has as of late become progressively mainstream and

scatter in the wake of quicker and less expensive

web associations and better advances. Current

independent video conferencing units give

progressed video and sound quality due to more

productive pressure and can work over typical

broadband web associations. Developing preparing

power and less expensive embellishments, like

webcams, have additionally made it conceivable to

partake in a video meeting utilizing committed

programming on a ordinary Android TV with no

costly unique equipment. With the financial plan

extended to the limit, a few business premises and

establishments are settling to the side their

movement plans and going to web conferencing to

set aside cash and time. Video meeting members use

either VC framework, electronic application or on-

premises programming to intuitively speak with

collaborators, understudies and others in virtual

gatherings or study halls.

This methodology is simpler, less expensive

furthermore, considerably more advantageous to

utilize while additionally giving simple access to

record sharing and assortment of others

communitarian administrations. With the blast of

data transfer capacity, the assets are presently

accessible to give more communication in the virtual

study hall by means of video conferencing. Utilizing

the different innovations accessible for video

conferencing, researcher can give a more intelligent

distance learning experience by conveying

continuous, bidirectional video, voice, and

information correspondences to their distance

understudies, instead of simply the standard

electronic media. Video-based remotely

coordinating is a type of remotely coordinating done

through mediums that help video and sound

correspondence. It is a live video association

between individuals in separate areas with the end

goal of correspondence or communication (Sami

Andberg, 2008).

2 LITERATURE REVIEW

Video conferencing is a generally new instructing

and learning advancement. Greenberg (2004)

proposed that "videoconferencing-based distance

schooling has been in the early appropriation stage

for a very long time or more Here is where things

were beginning to get muddled. Or then again so we

thought (Sami Andberg, 2008). It is essential to

comprehend the at the reason Jitsi could

undoubtedly turn into a conferencing blender, was

that the way toward blending sound is extremely

straightforward. It is really a matter of adding

numbers together. One necessity to give unique

consideration to keeping these numbers inside an

uncommon reach, or to not sending one's sound back

to themselves (which regularly implies creating

individual blends for each client) yet indeed, even in

view of that, sound blending remains an interaction

that is adequately lightweight to be dealt with by

ware hardware.

The circumstance is very different for video.

despite the fact that it has required some investment

to come to that end result. If we somehow managed

to deal with video conferencing the manner in which

we by and large handle sound, at that point we

would need to blend video content. The idea of

video blending is that of creating composite images.

As such, if clients A, B, C, and D were to take an

interest in a blended video conferencing call, at that

point they would each begin a regular balanced

meeting with the blender and send their video

streams to it obviously. In return, they would receive

a solitary video stream that would happen to contain

every other person's substance regardless of whether

somewhat downsized.

The straightforwardness, all things considered, is

very engaging for a customer: conferences are

similarly as some other call and no extraordinary

exertion is required to help them. Tragically things

aren't exactly so basic at the server side. The reason

is that video content blending requires a tremendous

measure of preparing resources. JRES 2013 -

Montpellier 2/8. When performing video content

blending, one necessity to decipher every single

approaching edge (one for every member), downsize

every single one of them, create composite images

and afterward re-encode them by and by (Sami

Andberg, 2008).

3 METHODOLOGY

Jitsi Meet is a JavaScript application that utilizations

WebRTC and can work with server’s dependent on

Jitsi Videobridge (a door to communicate video

transfers to video gathering members). We did the

tests on Jitsi Meet on a devoted server. The server

had every one of the administrations for Jitsi Meet:

web server (nginx), XMPP server (prosody) and Jitsi

Videobridge. During testing, we discovered the issue

with the Jitsi Videobridge, which is over-burden to

send an enormous enough measure of traffic.

Utilizing programs to fill enough gatherings will

probably require hundreds or even huge number of

PCs (Rachel Roberts, 2009). To tackle this issue, a

full star geography was utilized to make a gathering.

With this geography, inbound traffic from any

endpoint is engendered to any remaining endpoints

associated with Jitsi Videobridge. In this design, we

have streams A * (A-1) leaving the video connect

(and showing up A-1). Jitsi Videobridge - is a part of

the XMPP server, it permits you to sort out multi-

client video correspondence. Its distinction from

costly committed equipment video spans is that it

doesn't blend video channels into a composite video

transfer, however, just transfers the got video diverts

to all members in the call.

The force of the processor doesn't make any

difference for its work. Jitsi Meet backings

highlights, for example, work area and window

sharing, programmed video changing to the dynamic

speaker's video, community record altering in

Etherpad, show sharing, real time a gathering on

YouTube, sound conferencing, member network

through the Jigasi telephone passage, secret phrase

insurance, "talk at the hint of a catch" mode, URL

greeting sending, and text visit. All information

streams between the customer and the server are

encoded (expecting that the server is running all

alone limit). Jitsi Meet is accessible as a different

application (counting Android and iOS) and as a

ICICIS 2021 - International Conference on Innovations in Computer and Information Science

library for reconciliation into sites (Rachel Roberts,

2009). By and large, Jitsi is an incredible video

meeting, helpfully composed and effectively

inserted on Linux family frameworks. We made Jitsi

meet application window and gathering with

interconnection between clients, just as full web

usefulness accessible to members from the authority

Jitsi archive. We utilized the Make file to make an

application and set up everything, libraries, files.

3.3 Develop for Android

Android, this word means a lot in present High-Tech

World. Today Smartphone are known for its

operating system which is Android. Earlier there is

no option for operating systems like Android in

mobile, as usual there are symbian, java featured

operating systems but today things have changed a

lot, everyone wants a Smartphone which is

functioned on Android only. In a very short span of

Android TV App for Video Conferencing

time android created a reputed place in the market.

What is this Android actually? Android is a software

cluster for mobile devices that includes an operating

system OS, key applications and middleware (JNT

Association, 2007). The Android SDK provides the

tools and APIs required to begin developing applications

on the Android platform using the Java programming

language. About the design, Kernel of Android is based

on Linux kernel and further furnished by Google

(Greenberg. 2009). Currently an SDK is hosted by

Google, which is a leading player in the initiative. This

SDK allows creation of various Java based programs by

using a special Eclipse plug-in that interfaces with the

kit. Android is not only an OS but also includes a

middleware and an array of applications for the users

(Greenberg. 2009). Some of the supported features are –

a Dalvik Virtual Machine, built in browser and

database support, media, camera, GPS, maps and

other features.

Figure 3: Technologies Used.

3.4 Basics for Building a TV App

To make your application effective on TV gadgets,

you should plan new formats that can be handily

perceived from 10 feet away and furnish navigation

that works with simply a directional cushion and a

select catch.

3.4.1 Build a Great Search UI

The Learn back help library gives a bunch of classes

to empower a standard hunt interface inside your

application that is predictable with other pursuit

capacities on TV and gives highlights, for example,

voice input.

Figure 4: Android Tv UI.

3.4.2 TV Appropriate Apps

Applications most appropriate for TV offer vivid

diversion encounters. Applications that give getting

the hang of, playing, conveying, and substance

utilization are genuine models, however this is

anything but a thorough rundown (Lynne, 2007).

3.4.3 A Large Screen UX

Because of the survey distance of the TV, clients

will most likely be unable to measure as much data

on TV as they would on a PC or cell phone.

Breaking point the measure of text and perusing on

TV screens.

3.5 The Hardware Components

Fundamental gear required for a video meeting

incorporate a camera, receiver, a video conferencing

unit, show unit, and sound framework (JNT

Association, 2007; Alan, 2009).

3.5.1 Camera

A camera to catch pictures and convert them into an

electrical sign. Area of the camera must be ideal to

consider reasonable eye to eye connection.

Likewise, great quality and usefulness of the

cameras ought to have the option to give a more

honed, more brilliant picture, with less visual

commotion.

3.5.2 Microphones

Microphones utilized in VC are normally touchy and

should be set away from supplies like projectors

which can create some foundation commotion.

3.5.3 Video Conferencing Unit

The VC unit normally alluded as the codec

(Coder/Decoder) acknowledges the vision and sound

signs (video and sound) and cycles them into a

reasonable configuration for transmission through the

organization to the distant site. To get data the Decoder

does the converse: it acknowledges the computerized

signals from the distant site over the organization and

unravels or changes over these into video and sound. At

last this video and sound are taken care of to a showcase

unit and speaker to show the photos and replicate the

sound from the distant site separately.

3.5.4 Display Unit

A showcase unit can be either a TV unit or a

ICICIS 2021 - International Conference on Innovations in Computer and Information Science

projector anticipating onto a surface. The display

unit is associated onto the codec.

3.5.5 Sound System

A decent sound framework is ideal for video

conferencing. In certain occurrences, TV speakers

are utilized however in many occurrences (for

example homeroom, meeting rooms, and so on), a

decent sound framework with blender, enhancer

furthermore, speakers may be required.

Figure 5: UI Components of the Android Tv.

3.6 Jitsi Meet

Figure 6.

The initial step to an answer, was to check whether

utilizing a different application would prompt better

results. All Japanese understudies have LINE, it is

by a long shot the most mainstream courier

application in Japan. In any case, as instructors, we

preferred not to request understudies to give up their

own LINE ID to individuals that they may not wish

to do as such. Google Hangouts had just required

them to share a school provided email address which

is undeniably less intrusive. Thus, Jitsi Meet was

chosen as the subsequent application, as it provided

greater protection to the understudies.

JitsiMeet (https://jitsi.org/jitsi-meet) is an open

source communicator that provides sound/video

conferencing ability, video streaming, text-based

visit, and file move. Jitsi Meet is a decent decision

for anybody with protection concerns. Jitsi Meet

doesn't require the understudies to share individual

email addresses or other individual data with

different understudies. Indeed, no record is required.

Conference individuals can without much of a

stretch create tweaked codes with letters and

numbers, and individuals would then be able to join

video conferences by just composing the provided

code. Survey from effortlessness and protection

points of view, it is a brilliant decision.

4 ANALYSIS

Getting information directly after the classes, the

first impression of the educator’s dependent on their

experience was that Jitsi Meet had less issues than

Google Hangouts. Be that as it may, upon

investigation, the Jitsi Meet information appears to

agree definitely more intimately with the Google

Hangouts information than the educator experience

may have recommended. Basically, there were

undeniably more gadgets in use during the Jitsi Meet

investigation periods and this very likely prompted

more specialized troubles instead of a lack in Jitsi

Meet itself. There are three focuses that help this

end. Initially, the model container information. Jitsi

Meet had four times of information. Three periods

fall into the huge over-spill container four. There

were numerous issues on the grounds that there were

numerous gadgets being utilized (43-66 gadgets).

The fourth time of a day and a half, which

corresponds to can three, had 30.56% of hazardous

gadgets and was identical to the Google Hangouts

information for 36 gadgets. Besides, while 66

gadgets prompted 32 issue groupings, it is

additionally evident that 34 gatherings associated

effectively to Jitsi Meet rather than a high of 25 for

Google Hangouts.

Figure 7.

This would propose that Jitsi Meet was not any more

tricky than Google Hangouts, but instead Jitsi Meet

was utilized under greater stress creating a negative

response from the educators. At long last, the linear

regression investigation, dissipate plot,

unequivocally upholds this contention.

5 ANDROID TV VIDEO

CONFERENCING

Figure 8.

Android Tv Videoconferencing is a method of

communicating between two or more locations in

which sound, vision and data signals are conveyed

electronically to enable simultaneous interactive

communication? Much more personal and effective

than audio conferencing, all parties involved can see

the facial expressions and body language that are so

vital to the way we communicate (JNT Association,

2007). Video conferencing works by using a few

different technologies. Some of these technologies

are hardware while others are software related. A

Video conference can be between two sites, i.e.

locations which are connected to each other via the

video conference, or the conference can connect

multiple locations (Greenberg. 2009). The

communication can take place in a special video

conferencing studio, or on a normal home computer

equipped with a webcam or even a video call on a

modern 3rd generation mobile phone falls into this

scope (Roberts, 2009). Besides the audio and visual

transmission of meeting activities, allied

videoconferencing technologies can be used to share

documents and display information on whiteboards.

6 DISTANCE DELIVERY

The contention for conveying courses a good way

off utilizing videoconferencing alone is less

convincing. In certain areas, videoconferencing is

seen by instructors, directors, students, and the

bigger local area as a way to reproduce the study

hall experience a good way off – a fare work that

requires insignificant change in instructional method

also, study hall conduct. As one instructor clarified:

"I put on a façade for the students like all is Well

and made an effort not to treat it any distinctively

that a normal study hall." Early discoveries,

nonetheless, show that the video-conferencing

experience is inalienably unique in relation to

homeroom educating and, much of the time, more

trying for instructors and students. "I felt very

unsteady the main day. (Rachel Roberts, 2009) It

likely took me a month to be agreeable in there",

said another instructor. The scientists' experience as

distance instructors moreover drives them to contend

that videoconferencing can be utilized as just one

instrument in a set-up of many distance training

innovations.

Figure 9. Remote Learning.

6.1 Teaching Benefits

Educational video conferencing provides teachers

with more flexibility as they are able to convey ideas

and subject matter without the boundaries of

distance (Rosenberg et al., 2008). The daily

commute that some teachers typically make to reach

their place of employment is eliminated when their

options for reaching students are expanded. For

example, one lecture could teach to all fourth-year

university students in four different school buildings

across campus simultaneously (Rosenberg et al.,

2008). Time and money can be saved along with the

same subject matter not having to be taught to each

class independently. Evening lessons may be

provided as teachers could provide lessons via VC

from home.

6.2 Real-world Education VC Benefits

Enabling Better Course Delivery

• Allows collaboration with other schools and

students worldwide.

• Organization of projects based around overseas

schools and their communities.

• Low-Cost Single Site-to-Site Setup, easily call

other schools via dial codes.

• Utilizes one originating teacher and a facilitating

teacher at each connected site.

• Small- and Large-Scale Solutions to suit primary,

secondary or higher education.

• Requires that students and the facilitating teacher

be active participants in the learning experience.

ICICIS 2021 - International Conference on Innovations in Computer and Information Science

• Face-to-Face communication allows students better

appreciation of other cultures, languages & dialects.

• Provides lessons (such as specific foreign

languages) which would not normally be catered for

due to staffing requirements or facilities.

• Allow teachers to attend meetings without the need

for travel & spend more time lesson planning etc.

7 CONCLUSIONS

Android Tv conferencing application could lead the

way of learning very effective and interactive. It will

give the responsibility for Video conferencing could

lead the way in both the approach, it will provide the

students effective way for their learning, or working

in a team, and also doing academic tasks, which

would be beneficial for teaching, for corporate

workers. It would not change the utilization of print

or different strategies utilized in the

conceptualization interaction. It may be utilized to

energize development and its actual use lies in

empowering exchange and expanding the distance

learning courses. With the use of broadband or

Internet Connectivity, Android Tv conferencing can

be possible in a very efficient way also the

accessibility of fast and modest web associations, it

is normal that video conferencing will progressively

become mainstream now a days, prompting more

revenue and utilization of distance learning. In this

paper, a prologue to video conferencing and its

application in distance learning was introduced as a

viable method of conveying topic in study halls or

work from home. In this Research work Jitsi is used,

which gives the vital programming to make your

own Android Tv video conferencing administration

that can be sent utilizing a virtual work. Jitsi meet is

an open-source program that permits you to get

sound/video calls and meetings, web based and work

area sharing, texting, and numerous others.

8 FUTURE SCOPE

Figure 10.

Android Tv Video conferencing is very useful video

conferencing task and acquiring reception is its first

significant test. Ideally, we would be ready to depict

video conferencing organizations in a future JRES

version. From an advancement viewpoint we desire

to have the option to address a few significant angles

like help for portable customers, Scalable Video

Coding (SVC) and additionally simulcasting,

retransmission procedures and huge scope

gatherings and instructing meetings. Making

Android Tv using Jitsi Video conferencing amicable

towards versatile customers would expect us to carry

out exchanged or specific video handing-off so just a

portion of the streams would be delivered on the

Android Tv. Comparable retransmission systems

would be needed for the help of on-line classes and

enormous scope meetings. SVC and simulcasting

would be significant for upgrading transmission

capacity utilization, improving blunder flexibility

and convenience for their users.
